Filed: 1955-04-06
Abstract: 768,891. Feeding sheets. STOLZ, A. April 6, 1955, No. 10097/55. Class 100(1) Apparatus for separating sheets from a pile comprises a rotatable or oscillatory hollow roller 1, Figs. 1 and 2, having pivoted on the periphery, on hollow pivots 3, two bell-crank arms 2, each arm carrying at one end two suction heads 4 and at the other end a follower 6 engaging a cam 7. The roller 1 is mounted for rotation on a fixed or rockable hollow shaft 8, and is driven from a shaft 16. The cam 7 is secured to the shaft 8. The shaft 8 is con nected to a source of suction, and suction is established in each head 4 through ducts in the arms 2, flexible tubes 14 leading from the hollow pivots 3 to the inside of the roller 1, a peripheral recess in a radial segment 9, and a radial passage in the segment which communicates with the inside of the shaft 8. The segment 9 is fixed to the shaft 8, and suction is established alternately to each arm 2 for a period sufficient to enable a sheet to be lifted from the pile and carried between feed rollers 15 and cam-actuated drop-feed rollers 17. Sheet-separation is assisted by air blasts from a tube 21 which is oscillated by a cam 22 and a pivoted two-armed lever 23. In a modification, Fig 6, there are two adjacent piles of sheets, two rollers 1 with suction separators constructed similarly to those described and arranged to separate sheets simultaneously or alternatively from the piles, and the separation is effected at the rear edges of the sheets instead of the front. A driving shaft 25 drives one roller 1 directly through gearing 26, 27, and this drives the other roller 1 through intermediate gearing 28. The conveyer rollers 15 are driven by a chain drive 29. An air blast tube 21 (not shown) is arranged above each sheet pile, and each is oscillated 'by a cam arrangement. A stop or abutment which bears against the front edge of each pile is oscillated to permit delivery of each sheet to the rollers 15. In the case where the hollow shaft 8 is rocked, the cam 7 and radial segment 9 fixed thereto exercise a control on the sheet-separation independently of the rotation of the roller 1.

Title: Fuel vaporizing assembly
Inventor: LAUDER ALFRED ERNEST
IPC: F02M33/06
Filed: 1962-03-16
Abstract: 936,712. Vaporizers. G. S. ELDRIDGE. March 16, 1962, No. 10119/62. Class 7(3). Fuel vaporizing apparatus for use in conjunction with an internal-combustion engine includes means for producing a metered mixture of air and atomized fuel, separating means 16 coupled to the producing means for receiving the metered mixture of air and atomised fuel therefrom and for exerting centrifugal forces on the mixture to separate the atomized fuel from at least a major portion of the air in the mixture, the separating means having a first outlet port 36 to which the separated fuel is directed and having a second outlet port 22 in which the separated air is directed, means coupled to the first outlet port of the separating means for heating the fuel therefrom to a temperature within a predetermined range to convert the fuel to a dry vapour phase and mixing means coupled to the second outlet port of the separating means and to the heating means for receiving the air from the separating means and the fuel vapour from the heating means the mixing means re-mixing the air from the separating means with the fuel vapour from the heating means and introducing the resulting mixture to the engine. When the throttle 12 is closed and the engine is idling the suction causes air to flow in through the tubular member 41 and through the tube 40 in the atomizing unit 30. As the throttle 12 is opened more fuel is supplied down the atomizing unit 30 together with a limited amount of air. This fuel/air mixture passes through the passageway 38 and is drawn by the vacuum through the outlet end of the atomizing unit 30. The fuel therefore emerges as a spray at the nozzle tip 42. The open portion of the tubular member 46 faces an elongated opening in the exhaust manifold 48 which opening is enclosed by the tubular member. The outlet of the heat exchanger 32 is coupled to a pipeline 64 which extends to a nozzle (not shown) in the mixing chamber 26. The pipeline 24 is also coupled to the mixing chamber 26 and this latter pipeline introduces the air from the separator chamber 16 into the mixing chamber.

Title: Improvements in or relating to cop winding machines
IPC: B65H54/36
Filed: 1941-08-11
Abstract: 548,478. Winding yarns. SCHARER, K. J., (trading as MASCHINENFABRIK SCHARER). Aug. 11, 1941. No. 10178. Convention date, June 18, 1940. [Class 120 (ii)] In a cop winding machine in which the thread guide is fed by a feeler means intermittently advanced along a partly screwed spindle, with which it engages by gravity, by contact with the yarn windings, the spindle is fixed and means is provided for lifting the screwed box of the feeder means in order to free the engagement thereof with the spindle on completion of the winding and to re-engage it therewith by lowering the box after the feeder means has been returned to its initial position; the box of the feeder.means may be threaded for a part of its length only and may be disengaged from the screwed spindle by lifting the end of the bore to incline it. As shown the thread guide carrier 5 is fixed to a sleeve 3 connected by a cone and ball clutch 8, 9 with the reciprocating traverse rod 1 and embraces a sleeve 12 on the partly screwed spindle 16 fixed in the machine frame. The conical feeler 10 is adjustably fixed to the sleeve 12 and at each reciprocation of the thread guide it contacts with the winding on the spool 26 and is fed along the spindle 16 contacting with the thread guide carrier 5, which is fed along the traverse rod 1 by momentarily overcoming the force of the spring 7 holding the sleeve 3 clutched to the traverse rod ; the feeler member 10 engages a wedge-shaped ring 5<SP>1</SP> on the carrier 5 so that the sleeve 12 tends to be tilted to bind the threaded portion 15 thereof on the thread of the spindle 16 and so prevent creeping of the feeler during engagement of the ring 5<SP>1</SP> with the member 10. The narrow threaded portion 15 in the central part of the sleeve 12 normally engages the threads of the spindle 16, but near the end of a winding operation a slide 20 is advanced so that a projection thereon encounters a pin 25 on the carrier 5 and moves it so that a lug 28 thereon engages a terminal cone 13 on the sleeve 12 and lifts the latter so that its threaded portion becomes disengaged from the threads of the spindle 16 and at rounded portion 14 at the other end of the sleeve bears on the spindle ; the lug 28 has sprung into a groove 13<SP>1</SP> in the cone 13 and return movement of the slide 20 causes a pivoted catch 22 thereon to engage the pin 25 and restore the sleeve 12, feeler 10, and thread guide to their initial position where the catch 22 is disengaged from the traverse rod, the feeler hits a stop on the spindle 16, the lug 28 becomes disengaged from the groove 13<SP>1</SP>, and the sleeve 12 falls back into engagement with the threads of the spindle 16. In a modification the thread guide carrier is fixed to a rod which passes through a hollow reciprocating shaft and is clutched thereto by a cone and ball arrangement which is momentarily disengaged from the rod at the end of each traverse.

Title: Improved control mechanism for supercharged aircraft engines
IPC: F02D9/00
Filed: 1944-05-26
Abstract: 597,930. Controlling change-speed gearing. GENERAL MOTORS CORPORATION May 26, 1944, No. 10296. Convention date, March 22, 1943. [Class 80(ii)] [Also in Groups XXVII and XXIX] Control mechanism for a supercharged aircraft engine includes a hydraulic servomotor for actuating change-speed mechanism in the supercharger drive, the servomotor being controlled by two valves, one of which is controlled by an aneroid, and the other in accordance with the position of the throttle valve whereby a change from low gear to high gear cannot be effected unless the throttle valve is adjacent its fully open position. In an embodiment, a bellows 28 sensitive to altitude actuates a valve 87 controlling the supply of pressure oil to a servo-piston 82 which, when moved to the right, pushes over a lever 94 loose on the operating shaft 93 of the changespeed mechanism 25 located in the drive between the engine 23 and the supercharger 21. The actual gear change is effected by a lever 27 which is fast on the shaft 93 but is connected to the lever 94 by a spring 97 so that a snap action will be given to lever 27 as it moves between stops 95; 96 defining the " low " and " high " gear settings, respectively. Actuation of the change-speed mechanism is prevented until the throttle 29 is fully open by allowing the pressure-oil supplied to the servo-piston to bleed away through a conduit 100 past a valve 102. The latter is closed when a projection 111 on the throttle valve shaft 40 strikes a three-arm lever 110 and rotates the latter until it contacts and moves the valve against its loading spring 104. A flexible link 108 between lever 110 and a lever 109 fast with lever 27 ensures that valve 102 is kept in the closed position once a change into high gear has been effected until the gear is changed back again into low by servo-piston 82. The boost and manual control of the throttle is similar to that described in Specification 597,929, [Group XXIX]. Shaft 93 is also connected by a lever 69, link 70, and a lever 71 to a shaft 72 which carries eccentrically the shaft carrying the cam 54 varying the datum of the boost control, thus maintaining a higher intake pressure when the supercharger drive is shifted into high gear.

Filed: 1919-04-24
Abstract: 147,997. Guye, F., Borel, L. H., and Ramseyer, H. April 24, 1919. Winding apparatus, electric.-The mainspring 5 drives the clock through the arbor c and to wind up the barrel b is turned by an electromotor on the worm-shaft d. The circuit is completed through two terminals 3, 4 by a spring- pulled key k under the control of a disk-cam i, which, being attached to a wheel h, is advanced by a bent finger b<1> on the barrel. As shown, the mainspring is partly wound up, and another revolution of the barrel will lift the key, but it will also turn a sleeve f with insulating-sector 9 so that the gap between two other terminals g is bridged. The mainspring is consequently further wound up till the sleeve is in the cut-off position again. During unwinding, an arm c<1> on the barrel-arbor c operates a star-wheel m engaging the cam-wheel h so that the cam is reversed to recomplete the circuit by means of the key. If the current fails, however, the reserve charge of the spring keeps the clock going till the rear step 11 of the cam lifts the key. The star-wheel is mounted on a spring arm n so that with each revolution of the barrel in winding an incline b<2> push it aside clear of the cam-wheel to let the bent finger b<1> act on the latter.
